Ever consider collecting all rent up front for a discount?

[Amir Navabpour]

I know that when a new tenant offers to pay upfront its a red flag. However, for an existing (good) tenant anyone ever consider offering a plan where rent can be paid in advance in return for a discount?  I am in software sales, and this is a common practice we employ when doing deals.  It can be for a 6 month or 1 year period, and have a sliding scale of discounts?  

Why I am thinking about this?  In my experience I have found even good tenants have life circumstance or unforeseen economic hits come that they are not prepared for.  With unemployment at a historical low, inflation remaining sticky and a Fed that is determined to slow down this economy I think it is a foregone conclusion that unemployment will go up substantially, meaning collecting rents can get harder.
